-// This is just a very thin wrapper over densehashtable.h, just
-// like sgi stl's stl_hash_set is a very thin wrapper over
-// stl_hashtable.  The major thing we define is operator[], because
-// we have a concept of a data_type which stl_hashtable doesn't
-// (it only has a key and a value).
-//
-// This is more different from dense_hash_map than you might think,
-// because all iterators for sets are const (you obviously can't
-// change the key, and for sets there is no value).
-//
-// NOTE: this is exactly like sparse_hash_set.h, with the word
-// "sparse" replaced by "dense", except for the addition of
-// set_empty_key().
-//
-//   YOU MUST CALL SET_EMPTY_KEY() IMMEDIATELY AFTER CONSTRUCTION.
-//
-// Otherwise your program will die in mysterious ways.  (Note if you
-// use the constructor that takes an InputIterator range, you pass in
-// the empty key in the constructor, rather than after.  As a result,
-// this constructor differs from the standard STL version.)
-//
-// In other respects, we adhere mostly to the STL semantics for
-// hash-map.  One important exception is that insert() may invalidate
-// iterators entirely -- STL semantics are that insert() may reorder
-// iterators, but they all still refer to something valid in the
-// hashtable.  Not so for us.  Likewise, insert() may invalidate
-// pointers into the hashtable.  (Whether insert invalidates iterators
-// and pointers depends on whether it results in a hashtable resize).
-// On the plus side, delete() doesn't invalidate iterators or pointers
-// at all, or even change the ordering of elements.
-//
-// Here are a few "power user" tips:
-//
-//    1) set_deleted_key():
-//         If you want to use erase() you must call set_deleted_key(),
-//         in addition to set_empty_key(), after construction.
-//         The deleted and empty keys must differ.
-//
-//    2) resize(0):
-//         When an item is deleted, its memory isn't freed right
-//         away.  This allows you to iterate over a hashtable,
-//         and call erase(), without invalidating the iterator.
-//         To force the memory to be freed, call resize(0).
-//         For tr1 compatibility, this can also be called as rehash(0).
-//
-//    3) min_load_factor(0.0)
-//         Setting the minimum load factor to 0.0 guarantees that
-//         the hash table will never shrink.
-//
-// Roughly speaking:
-//   (1) dense_hash_set: fastest, uses the most memory unless entries are small
-//   (2) sparse_hash_set: slowest, uses the least memory
-//   (3) hash_set / unordered_set (STL): in the middle
-//
-// Typically I use sparse_hash_set when I care about space and/or when
-// I need to save the hashtable on disk.  I use hash_set otherwise.  I
-// don't personally use dense_hash_set ever; some people use it for
-// small sets with lots of lookups.
-//
-// - dense_hash_set has, typically, about 78% memory overhead (if your
-//   data takes up X bytes, the hash_set uses .78X more bytes in overhead).
-// - sparse_hash_set has about 4 bits overhead per entry.
-// - sparse_hash_set can be 3-7 times slower than the others for lookup and,
-//   especially, inserts.  See time_hash_map.cc for details.
-//
-// See /usr/(local/)?doc/sparsehash-*/dense_hash_set.html
-// for information about how to use this class.
